[rules-users] every-distinct feature in drools fusion

[Elran Dvir]

Hi All,

I am checking different types of CEP engines.
In Esper there is a feature called "every-distinct" (http://esper.codehaus.org/esper-4.9.0/doc/reference/en-US/html/event_patterns.html#pattern-logical-everydistinct).
It basically finds an event relevant if the combination of defined field is unique.

Is there a similar feature in Drools Fusion?

Thanks.
